The First Lady appeared on The Tonight Show with Jimmy Fallon last night to discuss the fourth year of Let’s Move! and to encourage young people to sign up for the Affordable Care Act — but the sit-down chat isn’t what has people buzzing. Much like she’s done in past appearances with Fallon, Mrs. Obama also appeared in a viral-ready skit.

In yet another holdover from Late Night, Fallon brought back Ew!, his Saturday Night Live-esque teen girl talk show, where he and another guest (this time, Will Ferrell) pretend to be 13-year-olds and discuss matters of great importance to teens: Harry Styles, kissing posters of Harry Styles, etc.

The First Lady was a great sport in the silly sketch, and managed to give great face to the cameras, plug healthy snacks (Kale chips!), and, of course, even participated in a requisite dance party.
